The problem of photochemical smog is being addressed by authorities in the five major cities of Australia. Detrimental levels of smog are exceeded occasionally in the larger cities of Sydney and Melbourne, while the geographic features and meteorology of Brisbane, Perth and Adelaide suggest potentially unacceptable levels as those cities continue to grow. Motor vehicles are the dominant source of precursor emissions for smog and this is reflected in the comparison by Ahmet and van Dijk (1994) of hourly-averaged ozone exceedences for Australia`s major cities, i.e., the number of exceedences is roughly proportional to the population. Although statistics such as these can be strongly influenced by the distribution of monitors within a network, the relatively low exceedence threshold (0.08 ppm) probably ensures that the results are a realistic indicator of the relative extent of the problem in each city.
